Regarding targeting RC doctrines that I find to be anti biblical, I've spend dozens of hours on FR doing that. Ultimately, I just wish "Christians" would read the bible a lot more.
They sure do in New England. I have asked a couple of Catholics who have their head screwed on straight why that is true...they shrug and say "Got me..."
You can't blame an institution for individuals that stray. Jesus associated with prostitutes, tax collectors and thieves. As far as Catholics voting Democrat, not all do. That's too wide of brush you're painting with. With that said a local Catholic Church has a network of services for illegal aliens. I'm sure they think they are doing the right thing. I think the point I'm trying to make is we are individuals. We will be judged as individuals, not by denomination. There won't be a Catholic section and a Protestant section in Heaven. The One True Church won't be on the internet touting itself as just a little better than the other guys.
I believe most Catholics vote Democrat.They used to, but that was before the legalization of abortion. However, some refuse to leave the party, anyway. These are Catholics that are not deep in their faith.
